I want to create a Python program which takes in multiple lines of user input. For example:

This is a multilined input.
It has multiple sentences.
Each sentence is on a newline.

How can I take in multiple lines of raw input?

sentinel = '' # ends when this string is seen
for line in iter(raw_input, sentinel):
    pass # do things here

To get every line as a string you can do:

'\n'.join(iter(raw_input, sentinel))

Python 3:

'\n'.join(iter(input, sentinel))

How do I read multiple lines of raw input in Python?, sentinel = '' # ends when this string is seen for line in iter(raw_input, sentinel): pass # do things here. To get every line as a string you can do: In Python, to provide multiple values from user, we can use − input() method: where the user can enter multiple values in one line, like − >>> x, y, z = input(), input(), input() 40 30 10 >>> x '40' >>> y '30' >>> z '10'

Keep reading lines until the user enters an empty line (or change stopword to something else)

text = ""
stopword = ""
while True:
    line = raw_input()
    if line.strip() == stopword:
        break
    text += "%s\n" % line
print text

How do I read multiple lines of raw input in Python?, I want to create a Python program which takes in multiple lines of user input For exampleThis is a multilined inputIt has multiple sente It will work only if you are expecting input with a minimal structure so that you can define a rule to test if the input is complete or if you must wait for another line. You can't replace the colon by enter because when you paste a text, raw input will read only up to the first ' ' in the text.

Alternatively,You can try sys.stdin.read()

import sys
s = sys.stdin.read()
print(s)

How to Read Multiline User Input in Python 2 and 3?, Let's do that! Taking user input for the multiple lines is not difficult in Python. And here is a simple code to get this done… Code for Reading Multiline  One thing to note in above Python code is, both x and y would be of string. We can convert them to int using another line. x, y = [int(x), int(y)] # We can also use list comprehension x, y = [int(x) for x in [x, y]] Below is complete one line code to read two integer variables from standard input using split and list comprehension

Just extending this answer https://stackoverflow.com/a/11664652/4476612 instead of any stop word you can just check whether a line is there or not

content = []
while True:
    line = raw_input()
    if line:
        content.append(line)
    else:
        break

you will get the lines in a list and then join with \n to get in your format.

print '\n'.join(content)

Reading multiple lines of input : Python, The problem is, I can't figure out how to read the multiple line input test cases x global operation #get input input = raw_input() input = input.split() #determine  This function helps in getting a multiple inputs from user . It breaks the given input by the specified separator. If separator is not provided then any white space is a separator. Generally, user use a split () method to split a Python string but one can used it in taking multiple input. input ().split (separator, maxsplit)

Try this

import sys

lines = sys.stdin.read().splitlines()

print(lines)

INPUT:

1

2

3

4

OUTPUT: ['1', '2', '3', '4']

python, You can read multiple lines with multiple raw_input and have a function which tests if input is complete. Here is an example # 2.1 Write a program to prompt the user for his or her name using raw_input. Also, prompt the hours and rate per hour using raw_input to compute gross pay. Use 35 hours and a rate of 2.75 per hour to test the program (the pay should be 96.25). You should use raw_input to read a string and float() to convert the string to a number.

How to input multiple values from user in one line in Python , Below is complete one line code to read two integer variables from standard input using split and Note that in Python 3, we use input() in place of raw_input​(). The easiest way to read multiple lines from a prompt/console when you know exact number of lines you want your python to read, is list comprehension. lists = [ input() for i in range(2)] The code above reads 2 lines.

How to take multiline input from a user and assign it to a single , Originally Answered: How can I take multi line input from user and assign to a single variable in python? Come on man, it's easy. >>>A=input(' ' ' Enter the input​  How to read input from the keyboard python 3: In python 3: raw_input() function was renamed to input() and it always returns the type as string. And old input() function was removed. Note: No confusion, there is no multiple functions to read input from keyboard in python 3 only one is input().

How to get an unknown number of input entries in Python, from sys import stdin; lines = stdin.read().splitlines(). 10.7k views · View 13 my_input=raw_input() #take next input. 18.9k views · View 9 How can I take multiline input from a user and assign it to a single variable in Python? 4,210 Views. There are two functions in Python that you can use to read data from the user: raw_input and input You can store the results from them into a variable. For Python training, our top recommendation is DataCamp. Datacamp provides online interactive courses that combine interactive coding challenges with videos from top instructors in the field.

Comments
  • If you're taking multiple lines of input, how do you know when the input has ended?
  • Have a loop that takes raw_input until the user enters 'done' or something.
  • I guess you're aiming for user input, but you can add newlines \n to the prompt, eg: raw_input('foo\nbar: ')
  • @felix001 Do you only want raw_input solutions or would you be fine with taking the input directly from stdin?
  • you could try this link daniweb.com/software-development/python/threads/269208/…
  • I've been a pythonista for about 6 years now and I never knew of this other form of iter(). You sir are a bl--dy genius!
  • How do I set EOF as the sentinel character?
  • @Randy You can it just won't look as pretty iter(lambda: raw_input('prompt'), sentinel)
  • Note that in Python 3, raw_input is now input.
  • @wecsam Added that in now to make answer complete for all pythons
